Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

The peCOD (photoelectric Chemical Oxygen Demand) method for COD analysis is well suited to the soft drink industry as it provides plant operators with quick and reliable COD results important for process monitoring and control. Continuous COD monitoring of wastewater can protect production plants by ensuring COD discharge levels meet the acceptable limits, and by detecting product leakage. It can ...

Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively ...

No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...

The increasing awareness of the public of environmental issues such as CO2 emissions, carbon footprints and waste recycling has brought the issue of environmental noise to the fore. Many of the demands of modern society result in the creation of noise sources such as larger airports, additional power stations and higher road traffic levels. In addition to this, the expansion of towns and cities, ...

The first automated station for water quality monitoring located in Beli Brod on the Kolubara river has launched on July 2008. The station was established as the result of RHMSS participation in Twinning project financed by EU, where RHMSS was entrusted with the Component 2 of this project. Installed equipment continually records values of water level, temperature, pH, electroconductivity and ...

The Situation A municipal power plant in the southern United States operates more than 10 stationary power plant engines capable of producing 52 megawatts of electric power. The plant is part of a larger statewide power grid system. Within the grid, the municipality brokers the purchase or sale of power hourly, based on the needs of municipality and the market rate for power on the grid ...

As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

The Wallensteingraben was originally constructed as a channel and is almost 20 km long. In the context of implementing the European Water Framework Directive, goals include improving ecological passability. At the same time a measurement site for the continuous monitoring of discharge quantities was installed. Products used include OTT SLD, OTT CBS and OTT LogoSens. Monitoring ...

Many pollutants such as CO2, NOx and SO2 have been monitored continuously already for decades. In the last years the awareness for the need to measure mercury has also grown, and continuous mercury monitoring is becoming more and more relevant. Especially industries burning coal, oil or waste, share the responsibility to monitor their mercury emissions. All measuring techniques need to be able to ...

Jefferson National Laboratory is a high tech laboratory located on a beautiful campus in suburban Virginia. Their research is centered on their high-energy electron accelerator. Energies generated are as high as 6 Gev continuous with currents up to 200 micro Amps. Where does the high-energy accelerator beam go after smashing atoms in the experimental sample? It impacts into a tank of purified ...

A new system for the detection of septic sewer overflows (SSOs) and unauthorized intrusions of manholes has been developed jointly with public water agencies in San Diego County, California. The goal of the project is to provide detection of SSOs early enough to deploy personnel to provide preventative action. The system has been in operation since May of 2005 and has detected and, with field ...

With a total volume of approximately 20 million cubic meters of water and a length of 450 meters, the reservoir supplies drinking water for 200.000 people in the area and fulfils also an important function in the flood protection there. With the new monitoring solution it was possible to reduce the workload and cost for collecting, reading out and transmitting of data significantly. An ...

Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...

The measurement capabilities of oil-in-water analysis methods are described by several analytical figures-of-merit. Examples are: Range (Linear and Dynamic) Limit of Detection (LOD) Limit of Quantification (LOQ) Precision (Repeatability and Reproducibility) Sensitivity Accuracy Response Time Some or all of these are often specified by customers in the bid packages issued when selecting a ...
